RING-SPINNING FRAME.

SPECIFICATION forming part of Letters Patent No. 415,419, dated November 19, 1889.

Application filed July 15. 1889. Serial No. 3] 7,541. (No model.)

To all who/It it hung/concern.-

Be it known that I, AMBROSE J. Nrcnons, of New Market, county of Rockingham, State of New Hampshire, have invented an Improvement in Ring-Spinning Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide a ring-spinning frame with means whereby bowing out of the yarn may be restrained v and the yarn be softened, and at the-same time drag be put upon the yarn to insure better and more compact winding, and that without increasing the tension on the yarn at the rolls.

In accordance with my invention I have provided a spinning-frame with a yoke which is located above the usual ring and traveler, the said yoke surrounding the bobbin, the feet of the yoke being attached to the ringholder, so that the yoke may not only be adjusted in unison with the ring on the ringrail, but so that the said feet may act to keep the traveler clear.

Figure 1 shows a sufficient portion of a spinning-frame with my improvements added to enable my invention to be understood. Fig. 2 is a top or plan view, enlarged, of my improved yoke mounted on a ring-holder; and Fig. 3 is a section in the line or, Fig. 2.

The rail A, upon which is secured the supporting case or holder B, to receive the foot of the spindle C, shown as of the sleeve-whirl class, the ring-rail D, the ring E, the traveler t, the ring-holder h, the bobbin G, and the guide-eye H, are and may be all as common in ring-spinning frames of usual construction.

In accordance with my invention I have surrounded the bobbin above the usual ring with a separatonyoke a, having feet or legs a, which, as herein shown, are attached to the ring-holder 72, so as to beach ustable in unison with the holder and the ring on the usual ring-rail, to which rail the said holder in practice will be secured by usual screws, as 3, in the slots 4, one of the said screws being shown in Fig. 1. The yoke is slotted, as at 5, the said slot being preferably diagonal, as

shown in Fig. 2, to enable the yarn y to be led readily to the inner side of the yoke, so that the yarn between the usual traveler and guide-eye may travel in the space between the inner side of the yoke and bobbin and yet not escape, the said yoke acting to substantially completely surround the bobbin and prevent not only the bowing out of the yarn, so as to hit against and break down the yarns of adjacent spindles and bobbins, but also to prevent the escape of yarn outwardly through the yoke during the rotation of the spindle. The inner edge of the yoke (see Figs. 2 and 3) is provided with a series of inclined serrations or teeth resembling screwthreads, the said teeth being inclined from top to bottom of the yoke, the upper ends of the teeth being inclined in the direction of rotation of the traveler. As the yarn is carried around inside the yoke in usual manner these teeth, owing to their inclined direction, produce a certain amount of drag upon the yarn on its way to the traveler, the drag being almost entirely between the yoke and the traveler and not extending up to the rolls, the inclined teeth acting in a measure to lift on the yarn being carried over them or to screw the thread up toward the rolls, thus producing an increase of tension in the yarn at the point where it winds upon the bobbin, and that without increasing the tension at the rolls. These serrations 0r teeth by their action upon the yarn also in a measure loosen the external fibers of the yarn, giving it an appearance of mule-spun yarn, the serrations also clearing off any motes or imperfections in the yarn, thus leaving the same clear before its arrival atthe traveler.

The legs of the yoke attached to the ringholder close to the line of travel of the traveler also act to keep the traveler clear of motes and lint.

I am aware that separators substantially semicircular in shape have been employed; but a separator which does not surround the bobbin cannot act as does my improved yoke.

The yoke herein shown is represented as composed of sheet metal and its legs or supe porters integral therewith.

I do not broadly claim a yoke-shaped separator; but prior to my invention I am not aWare that such a separator has ever been supported by a ring-holder or that such a separator has ever been provided ith a series of serrations at its inner edge to act as herein described, or that the legs supporting the yoke have ever been attached to a ring-holder and so located with relation to the ring and traveler thereon as to act as a traveler.

I claim 1. The combination, with a spindle, a ringrail, a ring-holder, a ring therein, and a traveler, of a separator-yoke a, secured to the ring-holder and substantially completely sur-' rounding the bobbin, to operate substantially as described.

clearer for the 2. The ring-rail, the adjustable ring-holder thereon, the ring in the said holder, the trav- Vitnesses.
